Title: Low frequency amplifying circuit
Inventor: NAKASHIMA SHIGERU
IPC: H03F1/30
Filed: 1981-03-06
Abstract: PURPOSE:To prevent the generation of a harsh sound by eliminating the distortion of an input signal waveform when a low frequency amplifying circuit is powered up, by applying a voltage to the bias circuit of the low frequency amplifying circuit without passing the voltage through a ripple filter circuit in a transient state. CONSTITUTION:A ripple filter circuit consists of a resistance R12, a capacitor C4, and a transistor (TR) Q3, and resistances R1-R4 and TRs Q1 and Q2 form a bias circuit. A TRQ4 is biased through a resistance R5 to amplify a signal inputted from an input terminal 1 through a capacitor C1. The TRQ4 is supplied with a power voltage from the TRQ3 through a load resistance R6, and a diode is connected in series between the collector and base of the TRQ3. When the circuit is powered up, diodes D1 and D2 are turned on until the circuit becomes steady, and thus the distortion of an input signal waveform is eliminated, thereby preventing the generation of a harsh sound.

Title: Digital telephone exchange
Inventor: YOSHIDA YOSHINORI
IPC: H04Q11/04
Filed: 1978-03-24
Abstract: PURPOSE:To secure the integration of the conversion signal processes regardless of the types circuits and thus to simplify the maintenance by converting signal bit  pattern of the PCM circuit so that it may be regarded equivalent to the trunk circuit operation input/output pattern of the individual analog circuit corresponding  to each channel. CONSTITUTION:Memory MEM corresponds to the channel of the PCM circuit to memorize the type of the signal system of the channel. Converter circuit CVL converts the channel signal bit of the PCM circuit based on the contents of memory MEM so that the signal pattern may be regarded equivalent to the trunk circuit operation input/output pattern of trunk circuit LPICT for the loop circuit and then transmit the pattern to time-division channel TDSW as the digital bit signal via branch insertion circuit D/I. Thus, the signal bit pattern of the PCM circuit is converted so that it may regarded equivalent to the trunk circuit operation input/output pattern of the individual analog circuit corresponding to each channel, and accordingly the conversion signal processes can be integrated regardless of the circuit type. As a result, the maintenance is simplified effectively.

Abstract: PURPOSE: To drive a load by a small-capacity coupling capacity without reference to an input clock period by connecting an auxiliary complementary transistor (TR) to a complementary output TR so that their base currents are supplied.  
     CONSTITUTION: When a rising pulse is inputted to a terminal IN, a complementary TRQ 11  turns on and its emitter current turns on an output TRQ 14  through a coupling capacitor C 13 . A voltage at an output terminal OUT, therefore, drops and an auxiliary TRQ 17  turns on to hold the TRQ 14  in an on state without reference to the charging of the C 13 . When the input pulse falls, a complementary TRQ 12  turns on and the TRQ 11  turns off. The emitter current of the  TRQ 12  turns on an output TRQ 13  through a coupling  capacitor C 11 . Simultaneously, the charge of the C 13  is applied as a backward voltage between the  base and emitter of the TRQ 14 , which turns off to raise the voltage at the  terminal OUT; and the auxiliary TRQ 17  turns off and an auxiliary TRQ 16  turns  on to hold the TRQ 13  in the on state, so that the input signal having its waveform inverted appears at the terminal OUT.
